【０００３】[0003]
従来の管継手１では、離脱防止具５とアーム８とが互いに独立して形成されて いるため、部品点数が多い。したがって、施工性が悪く、しかもコスト高である という問題点があった。 それゆえに、この考案の主たる目的は、施工性を向上でき、しかもコストを低 減できる、管継手を提供することである。 In the conventional pipe joint 1, since the detachment prevention tool 5 and the arm 8 are formed independently of each other, the number of parts is large. Therefore, there is a problem that the workability is poor and the cost is high. Therefore, the main object of the present invention is to provide a pipe joint that can improve workability and reduce cost.
【０００４】[0004]
この考案は、ゴム輪受容部とゴム輪受容部より奥部に形成されるかつパイプの 先端を空隙を有して受容する拡径部とを含む受口を有する継手本体、ゴム輪受容 部に受容されるゴム輪、受口の外面に形成される係止部、および受口に差し込ま れたパイプの外面に係止されるサドル部とサドル部から一体に延びて伸縮代を確 保して係止部に係合する係合部とを有する離脱防止具を備える、管継手である。 This invention provides a joint body having a rubber ring receiving portion and a receiving opening formed in a portion deeper than the rubber ring receiving portion and having an expanded diameter portion for receiving the tip of a pipe with a gap, and the rubber ring receiving portion. The rubber ring that is received, the locking part that is formed on the outer surface of the receiving port, and the saddle part that is locked to the outer surface of the pipe inserted into the receiving port and the saddle part extend integrally to secure the expansion and contraction allowance. It is a pipe joint provided with the detachment prevention tool which has an engaging part which engages with a stop part.
【０００５】[0005]
離脱防止具のサドル部から一体に延びて係合部を形成し、この係合部を介して 離脱防止具と継手本体とを連結するようにしているので、従来技術において用い ていたアームは不要となり、部品点数を削減できる。 Since the engagement portion is formed by extending integrally from the saddle portion of the separation prevention tool and the separation prevention tool and the joint body are connected via this engagement portion, the arm used in the prior art is unnecessary. Therefore, the number of parts can be reduced.
【０００６】[0006]
この考案によれば、屈曲性および伸縮性を損なうことなく部品点数を削減でき るので、施工性を向上でき、しかもコストを低減できる。 この考案の上述の目的，その他の目的，特徴および利点は、図面を参照して行 う以下の実施例の詳細な説明から一層明らかとなろう。 According to this invention, the number of parts can be reduced without impairing the flexibility and stretchability, so that the workability can be improved and the cost can be reduced. The above-mentioned objects, other objects, features and advantages of the present invention will be more apparent from the following detailed description of the embodiments with reference to the drawings.
【０００７】[0007]
図１および図２を参照して、この実施例の管継手１０は、継手本体１２および 離脱防止具１４を含む。継手本体１２は、ゴム輪１６を受容するゴム輪受容部１ ８とゴム輪受容部１８より奥部に形成されるかつパイプ２０の先端を空隙を有し て受容する拡径部２２とを有する受口２４を含む。受口２４の奥端部外面には、 フランジ２６が形成され、フランジ２６には取付ボルト等を通す孔２８が形成さ れる。また、受口２４の開口端部外面には、周方向に分布する複数（この実施例 では４つ）の係止部３０が形成される。 With reference to FIGS. 1 and 2, the pipe joint 10 of this embodiment includes a joint body 12 and a separation preventing tool 14. The joint body 12 has a rubber ring receiving portion 18 for receiving the rubber ring 16 and an enlarged diameter portion 22 formed deeper than the rubber ring receiving portion 18 for receiving the tip of the pipe 20 with a gap. It includes a socket 24. A flange 26 is formed on the outer surface of the rear end of the receiving port 24, and a hole 28 through which a mounting bolt or the like is inserted is formed in the flange 26. Further, a plurality of (four in this embodiment) locking portions 30 distributed in the circumferential direction are formed on the outer surface of the opening end portion of the receiving port 24.
【０００８】 離脱防止具１４は、半割りリング状の第１部分１４ａと第２部分１４ｂとの組 み合わせによって構成され、パイプ２０の外径とほぼ等しい内径を有する環状の サドル部３２を含む。サドル部３２の内面には、周方向に延びる滑り止め用の複 数の突起３４（螺旋状の溝等であってもよい）が形成され、サドル部３２の外面 には、継手本体１２の係止部３０と係合する複数（この実施例では４つ）の係合 部３６がサドル部３２から一体に延びて形成される。係合部３６は、アーム部３ ８を含み、アーム部３８の軸方向端部内面に突出して、継手本体１２の係止部３ ０と係合する爪４０が形成される。また、係合部３６の少なくとも１つには、離 脱防止具１４の回転を防止するための爪４２がアーム部３８の周方向両端部内面 に突出して形成される。なお、アーム部３８の長さは、パイプ２０を含む管路の 伸縮を吸収し得る所定長さに設定され、爪４０および４２の内径は、パイプ２０ の屈曲を吸収し得るように受口２４（ゴム輪装着部１８）の外径よりもやや大き く設定される。The separation preventing tool 14 is configured by a combination of a first part 14 a and a second part 14 b in the shape of a half ring, and includes an annular saddle portion 32 having an inner diameter substantially equal to the outer diameter of the pipe 20. . On the inner surface of the saddle portion 32, a plurality of projections 34 (which may be spiral grooves or the like) for preventing slippage extending in the circumferential direction are formed, and on the outer surface of the saddle portion 32, the engagement of the joint body 12 is performed. A plurality of (four in this embodiment) engaging portions 36 that engage with the stoppers 30 are integrally formed from the saddle portion 32. The engagement portion 36 includes the arm portion 38, and a claw 40 that protrudes to the inner surface of the axial end portion of the arm portion 38 and engages with the locking portion 30 of the joint body 12 is formed. In addition, at least one of the engaging portions 36 is formed with a claw 42 for preventing the rotation of the detachment preventing tool 14 so as to project from the inner surface of both end portions of the arm portion 38 in the circumferential direction. The length of the arm portion 38 is set to a predetermined length capable of absorbing the expansion and contraction of the conduit including the pipe 20, and the inner diameters of the claws 40 and 42 are set so that the bending of the pipe 20 can be absorbed. It is set to be slightly larger than the outer diameter of the (rubber wheel mounting portion 18).
【０００９】 パイプ２０の接合時には、図３に示すように、継手本体１２の受口２４にパイ プ２０を所定位置まで挿入し、係止部３０がアーム部３８の軸方向中央に配置さ れるように離脱防止具の第１部分１４ａと第２部分１４ｂとでパイプ２０を挟む 。そして、ボルト・ナット４４を用いて第１部分１４ａと第２部分１４ｂとを接 続する。At the time of joining the pipes 20, as shown in FIG. 3, the pipe 20 is inserted into the receptacle 24 of the joint body 12 to a predetermined position, and the locking portion 30 is arranged at the axial center of the arm portion 38. In this way, the pipe 20 is sandwiched between the first portion 14a and the second portion 14b of the separation preventing tool. Then, the first portion 14a and the second portion 14b are connected using the bolts and nuts 44.
【００１０】 施工後、パイプ２０を含む管路が加熱される等によって伸長すると、パイプ２ ０が受口２４の奥部へさらに挿入され、管路の伸長分が吸収される。一方、管路 が冷却される等によって収縮すると、パイプ２０が受口２４から引き出され、管 路の収縮分が補われる。パイプ２０の挿入時および引き出し時には、パイプ２０ の移動に伴って離脱防止具１４が移動される。そして、パイプ２０が一定長さ引 き出されると、離脱防止具１４の係合部３６（爪４０）が係止部３０に係合され る。したがって、パイプ２０はそれ以上引き出されない。また、不等沈下等によ ってパイプ２０が屈曲すると、パイプ２０の屈曲に離脱防止具１４が追従し、パ イプ２０に加わる曲げ応力が吸収される。After the construction, when the pipeline including the pipe 20 is expanded by heating or the like, the pipe 20 is further inserted into the inner portion of the receiving port 24, and the expanded portion of the pipeline is absorbed. On the other hand, when the pipe is contracted due to cooling or the like, the pipe 20 is pulled out from the receiving port 24, and the contracted amount of the pipe is compensated. When the pipe 20 is inserted and pulled out, the separation preventing tool 14 is moved as the pipe 20 moves. Then, when the pipe 20 is pulled out by a certain length, the engaging portion 36 (the claw 40) of the separation preventing tool 14 is engaged with the locking portion 30. Therefore, the pipe 20 is no longer pulled out. When the pipe 20 bends due to uneven settlement or the like, the separation preventing tool 14 follows the bend of the pipe 20 and the bending stress applied to the pipe 20 is absorbed.
【００１１】 この実施例によれば、離脱防止具１４のサドル３２と係合部３６とを一体に形 成するようにしているので、アームを用いていた従来技術（図１１）に比べて部 品点数を削減でき、したがって、施工性を向上できる。 また、係止部３０および係合部３６をそれぞれ４つずつ形成するようにしてい るので、１つ当たりの係止部３０および係合部３６の強度を小さくすることがで き、その結果、全体のサイズを小さくできる。According to this embodiment, since the saddle 32 and the engaging portion 36 of the detachment preventive tool 14 are integrally formed, compared with the prior art (FIG. 11) in which an arm is used, The number of parts can be reduced, and therefore workability can be improved. Further, since the four engaging portions 30 and the engaging portions 36 are formed, the strength of each engaging portion 30 and the engaging portion 36 can be reduced, and as a result, The overall size can be reduced.
【００１２】 さらに、部品点数を削減でき、しかもサイズを小さくできることから、製造コ ストを大幅に低減できる。 図４および図５に示す他の実施例の管継手５０では、上述の実施例における離 脱防止具１４に代えて、離脱防止具５２が用いられる。離脱防止具５２はパイプ ２０の外径よりやや大きい内径を有する環状のサドル部５４を含み、サドル部５ ４の内面には、パイプ２０の引き出し方向へ向かって縮径するテーパ面５６を有 するリング収納部５８が形成される。一方、サドル部５４の外面には、継手本体 １２の係止部３０と係合する複数（この実施例では４つ）の係合部６０がサドル 部５４から一体に延びて形成される。係合部６０は、アーム部６２を含み、アー ム部６２の軸方向端部内面に突出して、継手本体１２の係止部３０と係合する爪 ６４が形成される。なお、アーム部６２の長さは、パイプ２０を含む管路の伸縮 を吸収し得る所定長さに設定され、爪６４の内径は、パイプ２０の屈曲を吸収し 得るように受口２４（ゴム輪装着部１８）の外径よりもやや大きく設定される。 そして、離脱防止具５２のリング収納部５８には、ステンレス等の金属からなる 略Ｃ形状の離脱防止リング６６が収納される。離脱防止リング６６は、パイプ２ ０の引き出し時にパイプ２０の外面との抵抗が大きくなるように、たとえば図６ に示すような断面略鋸歯状に形成される。Further, since the number of parts can be reduced and the size can be reduced, the manufacturing cost can be significantly reduced. In a pipe joint 50 of another embodiment shown in FIGS. 4 and 5, a detachment prevention tool 52 is used instead of the detachment prevention tool 14 in the above-described embodiment. The detachment preventive tool 52 includes an annular saddle portion 54 having an inner diameter slightly larger than the outer diameter of the pipe 20, and the inner surface of the saddle portion 54 has a tapered surface 56 that is reduced in diameter in the pulling-out direction of the pipe 20. A ring storage portion 58 is formed. On the other hand, on the outer surface of the saddle portion 54, a plurality of (four in this embodiment) engaging portions 60 that engage with the locking portions 30 of the joint body 12 are integrally formed from the saddle portion 54. The engaging portion 60 includes an arm portion 62, and a claw 64 that protrudes on the inner surface of the axial end portion of the arm portion 62 and engages with the locking portion 30 of the joint body 12 is formed. The length of the arm portion 62 is set to a predetermined length capable of absorbing the expansion and contraction of the conduit including the pipe 20, and the inner diameter of the claw 64 is such that the bending of the pipe 20 can be absorbed. It is set to be slightly larger than the outer diameter of the wheel mounting portion 18). In addition, a substantially C-shaped separation prevention ring 66 made of metal such as stainless steel is stored in the ring storage portion 58 of the separation prevention tool 52. The separation prevention ring 66 is formed, for example, in a substantially sawtooth cross section as shown in FIG. 6 so that the resistance with the outer surface of the pipe 20 becomes large when the pipe 20 is pulled out.
【００１３】 図７を参照して、パイプ２０の接合時には、予め、離脱防止具５２を図７に示 す状態から係合部６０が継手本体１２の係止部３０と係合し得る位置に位置決め する。そして、たとえば図５に示すように、離脱防止具５２の回転を防止するた めの回転防止部材６８を２つの係止部３０の間に装着する。その後、パイプ２０ を離脱防止具５２のサドル部５４から継手本体１２の受口２４の所定位置まで挿 入する。Referring to FIG. 7, when the pipe 20 is joined, the separation preventing tool 52 is moved from the state shown in FIG. 7 to a position where the engaging portion 60 can engage with the engaging portion 30 of the joint body 12 in advance. Position. Then, as shown in FIG. 5, for example, a rotation preventing member 68 for preventing rotation of the separation preventing tool 52 is attached between the two locking portions 30. After that, the pipe 20 is inserted from the saddle portion 54 of the separation preventing tool 52 to a predetermined position of the receiving port 24 of the joint body 12.
【００１４】 施工後、パイプ２０を含む管路が加熱される等によって伸長すると、パイプ２ ０が受口２４の奥部へさらに挿入され、管路の伸長分が吸収される。一方、管路 が冷却される等によって収縮すると、パイプ２０が受口２４から引き出され、管 路の収縮分が補われる。パイプ２０の挿入時および引き出し時には、パイプ２０ の移動に伴って離脱防止リング６６（図４）が移動され、また、離脱防止リング ６６の移動に伴って離脱防止具５２が移動される。そして、パイプ２０が一定長 さ引き出されると、離脱防止具５２の係合部６０（爪６４）が係止部３０に係合 される。その状態からさらにパイプ２０を引き出そうとすると、リング収納部５ ８に形成されたテーパ面５６によって離脱防止リング６６が縮径され、その断面 略鋸歯状の内周部（図６）がパイプ２０の外面に食い込む。したがって、パイプ ２０はそれ以上引き出されない。また、不等沈下等によってパイプ２０が屈曲す ると、パイプ２０の屈曲に離脱防止具５２が追従し、パイプ２０に加わる曲げ応 力が吸収される。After the construction, when the pipeline including the pipe 20 is expanded by heating or the like, the pipe 20 is further inserted into the inner portion of the receiving port 24, and the expanded portion of the pipeline is absorbed. On the other hand, when the pipe is contracted due to cooling or the like, the pipe 20 is pulled out from the receiving port 24, and the contracted amount of the pipe is compensated. When the pipe 20 is inserted and pulled out, the separation prevention ring 66 (FIG. 4) is moved along with the movement of the pipe 20, and the separation prevention tool 52 is also moved along with the movement of the separation prevention ring 66. Then, when the pipe 20 is pulled out by a certain length, the engaging portion 60 (the claw 64) of the separation preventing tool 52 is engaged with the locking portion 30. When the pipe 20 is to be further pulled out from this state, the diameter of the separation preventing ring 66 is reduced by the tapered surface 56 formed in the ring housing 58, and the inner peripheral portion (FIG. 6) of the cross section of the pipe 20 has a substantially sawtooth shape. Cut into the outside. Therefore, the pipe 20 can no longer be drawn out. Further, when the pipe 20 bends due to uneven subsidence or the like, the separation preventing tool 52 follows the bend of the pipe 20 and the bending force applied to the pipe 20 is absorbed.
【００１５】 この実施例によれば、サドル部５４が環状の一体物として形成されるので、半 割り物をボルト・ナットで接続する等の手間を省くことができ、施工性をより向 上できる。 また、この実施例においても先の実施例と同様に、部品点数を削減でき、しか もサイズを小さくできるので、製造コストを大幅に低減できる。According to this embodiment, since the saddle portion 54 is formed as a ring-shaped integral body, it is possible to save the labor such as connecting the halves with bolts and nuts, and to improve the workability. . Also, in this embodiment, as in the previous embodiment, the number of parts can be reduced and the size can be reduced, so that the manufacturing cost can be greatly reduced.
【００１６】 図８〜図１０に示すその他の実施例の管継手７０では、離脱防止具７２のサド ル部５４に、リング収納部５８に貫通する孔７４（図９，図１０）が形成され、 リング収納部５８内面の孔７４近傍には、係止突起７６（図９）が形成される。 また、離脱防止具７２が受口２４の先端に当接した状態（図８）で、サドル部５ ４の奥部と受口２４の先端との間に所定の空間７８が形成される。In a pipe joint 70 of another embodiment shown in FIGS. 8 to 10, a hole 74 (FIGS. 9 and 10) is formed in the saddle portion 54 of the separation preventing tool 72 so as to penetrate the ring housing portion 58. A locking projection 76 (FIG. 9) is formed near the hole 74 on the inner surface of the ring storage portion 58. A predetermined space 78 is formed between the inner part of the saddle portion 54 and the tip of the receiving opening 24 in a state where the separation preventing tool 72 is in contact with the tip of the receiving opening 24 (FIG. 8).
【００１７】 この実施例によれば、リング収納部５８に貫通する孔７４が形成されるので、 孔７４から図示しない工具を挿入して離脱防止リング６６を拡径することができ 、それによって、離脱防止リング６６のパイプ２０外面への食い込み状態を解除 することができる。したがって、パイプ２０を受口２４に挿入した後でも、パイ プ２０を簡単に引き抜くことができる。According to this embodiment, since the hole 74 penetrating the ring housing portion 58 is formed, it is possible to insert a tool (not shown) from the hole 74 to expand the diameter of the separation prevention ring 66. It is possible to cancel the state in which the detachment prevention ring 66 bites into the outer surface of the pipe 20. Therefore, even after the pipe 20 is inserted into the receiving port 24, the pipe 20 can be easily pulled out.
【００１８】 また、離脱防止具７２が受口２４の先端に当接した状態でも、空間７８からチ ェックゲージを挿入することができるので、ゴム輪１６の装着状態を簡単に確認 することができる。 なお、上述したそれぞれの実施例では、継手本体１２をフランジ短管として形 成した場合を示したが、継手本体１２は、エルボ，チーズあるいはレデューサ等 の他の異形管として形成されてもよい。Further, even when the detachment preventive tool 72 is in contact with the tip of the receiving port 24, the check gauge can be inserted from the space 78, so that the wearing state of the rubber ring 16 can be easily confirmed. In each of the above-described embodiments, the case where the joint main body 12 is formed as the flange short pipe has been shown, but the joint main body 12 may be formed as another deformed pipe such as an elbow, cheese, or reducer.
